11/9/22 - This is a scarce and excellent Walther PPK with duraluminum frame. I call this one a "dual-tone" because the anodized finish shows a bright green on the frame, with a minty high-polish blue on the slide. The contrast is more striking than the photos show, and very cool looking. The frame shows minor thinning of the front strap, while the slide is near-mint. Excellent bore and early banner magazine with nice finger extension. The grip is in great shape but shows minor handling wear on the right side. Frame of the gun is marked GB, which stands for the Swiss dealer Gustav Burgin. Could denote guard issue or private purchase.
